Evacuation Trees with Contraflow and Divergence Considerations
(North Dakota State University, 2018)
In this thesis, we investigate how to evacuate people using the available road transportation network efficiently. To successfully do that, we need to design evacuation model that is fast, safe, and seamless. We enable the ...
Multiresponse Optimization Methodology Considering Related Quality Characteristics
(North Dakota State University, 2011)
Engineering problems often involve many conflicting quality characteristics that must be optimized simultaneously. Engineers are required to select suitable design parameter values which provide better trade-off among all ...
Impact of Integrating Zone Bypass Conveyor on the Performance of a Pick-To-Light Order Picking System
(North Dakota State University, 2012)
This thesis investigates the impact of integrating Zone Bypass (ZBP) conveyor to a Pick-To-Light (PTL) order picking system. This integration results in a new system (PTL+Z), which could be helpful to achieve higher levels ...
CFD Heat Transfer Simulation of the Human Upper Respiratory Tract for Oronasal Breathing Condition
(North Dakota State University, 2011)
In this thesis. a three dimensional heat transfer model of heated airflow through the upper human respiratory tract consisting of nasal, oral, trachea, and the first two generations of bronchi is developed using computational ...
Solder Joint Reliability: A Unified Thermo-Mechanical Model Approach
(North Dakota State University, 2014)
Due to an unprecedented pervasiveness of electronics in high performance applications, the dependability of mission critical equipment and systems, often solely depends on the reliability of underlying embedded electronic ...
A Domain-Knowledge Modeling of Hospital-Acquired Infection Risk in Healthcare Personnel From Retrospective Observational Data: A Case Study for Covid-19
(North Dakota State University, 2022)
Healthcare personnel (HCP) is facing a consistent risk of viral infections. We proposed a domain-knowledge-driven infection risk model to quantify the individual HCP and the population-level risks. For individual-level ...
Integration of Simulation and DEA to Determine the Most Efficient Patient Appointment Scheduling Model for a Specific Clinic Setting
(North Dakota State University, 2011)
This study develops a method to determine the most efficient scheduling model for
a specific clinic setting.
The appointment scheduling system assigns clinics' timeslots to incoming requests.
There are three major ...
Adaptive Production Planning and Scheduling for the Make-to-order DNA Manufacturing System
(North Dakota State University, 2010)
This thesis develops an adaptive production planning and scheduling system for the
make-to-order plasmid (DNA) manufacturing system. The system, which has stochastic
nature and random demand, was represented by a ...
Moisture Sensitivity of PLA/PBS Blends During Ultrasonic Welding and Fused Deposition Modeling
(North Dakota State University, 2021)
Moisture absorption into hygroscopic/hydrophilic materials used in fused deposition modeling (FDM) and ultrasonic welding (USW) can diminish desired mechanical properties. Sensitivity to moisture is dependent on material ...
Winter Road Maintenance System Design for Snow Plowing
(North Dakota State University, 2010)
Winter road maintenance is critical to ensuring safety and mobility of transportation
systems in regions with heavy snowfall. Winter road maintenance system design involves
several inter-related decision making problems ...
